WALL-PAPEEHANGING DEVICE;

Specification of Letters Patent.

rammed D'ec.3,1912.

Application filed March 13, 1911. Serial No. 613,959.

To all whom it may concem Be it known that we, WILLIAM J. DUNN and HENRYB. TAYLOR. both of the cityv of Montreal, in the Province of Quebec andDominion of Canada, have invented certain new and useful Improvements in\Vall- Paper-Hanging Devices, and do hereby declare that the followingis a full, clear, and exact description of the invention, such as willenable others skilledin the art to which it appcrtains to make and usethe same.

This invention relates to wall paper hanging machines and the object isto provide an improved means for discharging the trimmed and pastedpaper from the device.

A further object is to provide improved paper pasting means.

To accon'xplish these objects, a regulating scraper is provided in thepasting device and also a brush adapted to distribute the paste evenlyon the paper. At the front of the machine is an open frameworksupporting a carrier composed of a plurality of chains which engage thedamp paper and prevent it curling. at the same time carrying it out ofthe machine.

Referring to the drawings --Figure 1 is a vertical ectional view of thedevice. Fig. 2 is a partial plan view of same.

In the drawings, 3 designates a frame work suppo-rting the variousmembers of the pasting and trimming devices. The pasting devicecomprises a reservoir 4. containing a revolving drum over which thepapcris fed from the roll (5 by means of teed rolls 7 and idler rolls 8.On the ends of the feed rolls 7 are knives which trim the edges of thepaper smooth and parallel. After leaving the pasting device. the paperpasses through discharging rolls 9, and over a table 10, with which aknife 11 coi'iperatcs to cut the paper transversely at any desired pointBeyond the transverse cutting device. is the matching table. over whichthe paper passes in contactwith a tixcd sample thereof, in order thatthe precise cutting all point i may be determined. Formerly we made thismatching table in the form ot a plate having the matching aperturestherein. It was found thatv after a strip ot paper had been cut off, theend or the next freshly pasted strip, at'tcr passing over the transversecutting table, had a tcndcncv to url. This curling ot the paper not onlyruHlttl i As the paper leaves the the pattern side of the. curledportion but left some paste on the matching table where it would soilthe nncurled portion of the paper. To overcome this great disadvantage,we substitute for the solid table a dis charging conveyer consisting ofa number of endless chains 12, having comparatively large links. Thechains pass over sheaves 13 mounted on parallel shafts 14, one of whichis preferably driven from the discharge .rolls 9 by means of chaingearing 15. The drive is preferably soarranged that the chains 12 willhave a. greater surface speed than the discharge rolls 9.. After a stripof paper has been severed and removed, continued operation of the deviceimmediately projects the end of the new strip onto the chains 12. As thepaper is pasted on the upper side. any tendency to curl will throw theend of the strip downwardly between the links of the chains, where itwill be held by its own tendency to curl. Since the chainsl2travelfaster than the rolls 9 and therefore faster than the paper, thechains will have theeftect of straightening out the curl in the stripand'thus prevent the paper. from rolling up. After the paper passes overthe edge. 16 of the table, will overcome the tendency to curl. Thematching of the pattern of the paper is accomplished as before thesamples being held over the apertures 17 by meansof plates 18 andsprings 19.

Between the discharging rolls 9 and pasting device. is an adjustablecutter 20 for splitting the paper strip into two strips. In

' order to readily gage. the adjustment of this cutter. a slidable scale21 is provided, one end of whichmay be adjusted to the edge or thepaper. The cutter 20 is then positioned as desired according to thegraduations of the scale.

The improvement:- embodied in the pasting device comprise the use of astiff heavy bar 22 as a scraper for the paste roller 5. This bar isvertically adjustable by means of screws 23 passing through brackets 24horizontally adjustable on the framework 3. The bar 22 is preferablytriangular in cross section as shown in order that a sharp scraping ctlgc may be presented to the-roll 5. End scrapers 25 for the roll areslidably mounted on the scraping bar 0, and are sccurcd at any point byset screwslG.

paste roll 5, there is a certain amount of suction which combined withthe cohesion of the paste results in the paste being drawn intoirregular ridges on the paper. ridges, and equalize the distribution ofpaste, a brush 27 is provided at the rear of the paste reservoir andheld in place by brackets 28. This brush engages the pasted surface ofthe paper as itpasses over the rear idler 8, and distributes the pasteevenly. Any surplus paste which is removed by the brush falls into thereservoir.

Having thus described our invention, What we claim is i I 1. In a paperhanging machine, a paper pasting and trimming mechanism, a dischargingpaper conveyer, and means for holding a sample of the paper adjacent thepaper on said carrier. I

2. In a paper hanging machine, a paper feeding device, a paper pastingand trimming mechanism, and an endless discharging conveyer for thepasted paper traveling at a higher rate of speed than the paper.

3. In a paper hanging machine, a paper feeding device, a paper pasting ad trimming mechanism, an endless disc iarging conveyer for the pastedpaper traveling at a higher rate of speed than the'paper, and means forholding samples of the paper adjacent the paper on the conveyer todetermine the cutting ofi point.

4. In a paper hanging machine, a paper pasting, trimming and cutting offmechanism, a pattern matching device comprising a frame over Which thepasted paper travels, and means for holding samples of the paper inposition for the pattern of the pasted paper to register therewith todetermine the cutting off point and means on said frame To remove thesepaste for straightening out the curl of the paper caused by the wetpaste.

In a paper hanging machine, a paper feeding device. a paper pasting,trimming and cutting ofi mechanism, a matching device comprising a frameover which the pasted paper travels, means for holding a sample of thepaper on said frame in such position that the pattern of the pastedpaper may be matched to determine the cutting off point, and an endlessconveyer mounted on the frame and supporting the pasted pape", saidconveyer traveling faster than the paper.

(3. In a paper hanging machine, a paper pasting, trimming and cuttingoff meclrrnism, a skeleton frame, endless conveyer chains mounted onsaid frame, plates adapted to hold samples of the paper at the end ofthe frame, and springs clamping said plates to the frame.

7. In a paper hanging machine, a paper feeding device, a paper pasting,trimming and cutting off mechanism, a skeleton frame at the front of then'iaehine, shafts journaled therein, an endless chain conveyer mountedon said shafts and traveling at higher speed than the paper dischargedfrom the pasting and trimming incchanisn'i, plates for held ing samplesof the paper at the sides of the conveyer, and springs clamping saidplates to the frame.

In Witness whereof we have hereunto set our hands in the presence of twowitnesses.
